Pineapple-Grapefruit THC Sparkler

A one-glass, alcohol-free tropical sparkler with a chili-lime salt rim and a measured tincture dose, so you can work out the THC in your glass.

This THC mocktail recipe is a bright, adults-only tropical sparkler that trades the liquor for a measured tincture. Pineapple and grapefruit make a sweet-tart base, soda adds fizz and a chili-lime salt rim brings gentle heat. Five minutes, one glass, and a dose you can work out.

Dosing This THC Mocktail Recipe

Read the label for milligrams of THC per milliliter, or divide the bottle's total by its volume. For a lower-risk start, Health Canada points to products with a 2.5 mg THC ceiling. Swallowed in a drink, a tincture acts like an edible, so allow at least 2 hours before pouring a second.

Leave alcohol out; the CDC says the pairing likely impairs more than either alone. And because grapefruit can change how some medicines work, anyone on medication should ask a pharmacist or doctor about it first.

Ingredients

Use 100% juices; pink grapefruit runs a little sweeter than white. Agave dissolves easily in cold drinks, plain soda keeps things crisp, and chili-lime seasoning on a lime-moistened rim adds the kick. Not sure which tincture fits? Our tincture basics explain the types, and at our eight Michigan stores, budtenders can go over what's on the menu that day.

Make It

Salt just half the rim so each sip can be salty or not. The juices, agave and tincture get a 10-second shake before ice ever touches them; that step spreads the dose, though an oil-based tincture tends to float, so stir between sips. Strain over fresh ice and add soda. For more technique, see our guide to THC-infused mocktails.

Pitchers and Labels

One glass at a time is simplest. A batched pitcher gets an "infused" label showing the dose per glass, plus a spot of its own, apart from plain drinks and well out of children's and pets' reach.

Variations

  • Grapefruit only: double the grapefruit, drop the pineapple and add a touch more agave.
  • Pineapple-coconut: use coconut water in place of grapefruit.
  • Zero-THC: the same drink without tincture for guests who abstain, garnished differently so glasses never get mixed up.

Recipe

Makes
1 drink
Prep time
5 minutes

Ingredients

  • A lime wedge and 1 teaspoon chili-lime seasoning, for the rim
  • 3 oz (6 tablespoons) pineapple juice
  • 2 oz (¼ cup) pink grapefruit juice
  • 1 to 2 teaspoons agave syrup
  • A measured THC tincture (see the dosing note)
  • Ice
  • 3 oz (6 tablespoons) chilled soda water
  • A pineapple wedge, for garnish (optional)

Steps

  1. Run the lime wedge around half the rim of a glass and dip it in the chili-lime seasoning. Fill the glass with ice.

  2. Measure your dose with a marked dropper or, more precisely, an oral syringe.

  3. Shake the pineapple juice, grapefruit juice, agave and tincture in a shaker or lidded jar for 10 seconds, before adding any ice.

  4. Strain into the prepared glass.

  5. Finish with soda water, stir once and garnish.

Frequently asked questions

How much THC tincture goes in one drink?

Whatever your label math gives for your target. Example: a 30 ml bottle holding 200 mg, Michigan's adult-use cap for a tincture container, is about 6.7 mg per ml, so 0.3 ml adds about 2 mg. Use an oral syringe marked in tenths of a milliliter.

How long does a THC drink take to kick in?

Typically between half an hour and 2 hours, and Health Canada says reaching the full effect may take as long as 4 hours. After that, effects can last several hours. Sip slowly, keep a plain drink alongside, plan to stay in for the evening and don't drive.

Can I batch this for a party?

Yes, with care. Easiest is to batch the juice base plain and dose each glass as you pour, so guests skipping THC can share the pitcher. If you infuse the whole batch, add tincture for the exact number of glasses and stir before every pour.
